Please help, how to write correctly "Stay up-to-date with notifications" or "Stay up to date with notifications".
To me it seems to be an adjective here, therefore I would choose "up-to-date".
Please explain.

I would have picked the version with hyphens, because it looks ambiguous without them (i.e. the sentence can potentially be parsed as "stay up, in order to date...".) But that could be just me.
